Studies of a Nickel-Based Single-Molecule Magnet

Here we report the first example of catalytic metallogels, which are formed irreversibly in dimethylsulfoxide via the creation of cross-linked, three-dimensional coordination polymer networks by using transition-metal ions with multiple sites available for coordination and multidentate ligands. Conformational flexibility of the ligands and slow formation of the coordination polymers apparently favor the gelation, These metallogels are stable in water and most organic solvents and can catalyze the oxidation of benzyl alcohol to benzaldehyde by using, their Pd-II moieties as the catalytic centers. The best catalytic turnover of the metallogel is twice that of [Pd(OAc)(2)] under similar reaction conditions
